ESA says Euclid telescope discovered previously unknown comet C/2026 S1
The European Space Agency said its Euclid telescope discovered a previously unknown comet, later confirmed as C/2026 S1 (Euclid).
The European Space Agency said images captured by its Euclid space telescope in September revealed a previously unknown comet. The International Astronomical Union's Minor Planet Center confirmed the object on October 8 as C/2026 S1 (Euclid). ESA said it is Euclid's first discovery of a new comet, although the mission is primarily designed to study distant galaxies.
